Dreamcast Guides : Multi-Game Disc with XPD

Quick and dirty multi-game discs with XDP
by comradesnarky



First things first; game data ALWAYS goes in folders. All of the XDP files
should be in the root of the disc. Then you make folders there and put
 all
relevant game files in said folders.

This set is binhacked for 45000 LBA.

1. Edit XDP.INI. Go down to the [Launcher1] section. Leave the
"AppUrl="
line alone. For "AppDir=" it needs to be the folder that your game data
is in. "AppName=" is the name of the game's binary, which is usually

1ST_READ.BIN, of course.

2. The next part is dependent on your HTML skills. HTML is generally pretty
self explanatory for what it's doing, and it's not hard
to learn. Open
XDPDEX.HTML in some kind of text editor (or maybe some kind of web design
program if you're that fancy). You'll see that this is made up for
the
Gundam & DX 2-in-1 disc. You'll have to modify the HTML a bit to make it
 display text instead of blank boxes. I'll get to that in a second though.


This line:
<a href="x-avefront://---.dream/proc/launch/1">

Determines which game the link will launch. You probably noticed while
editing XDP.INI that there
are multiple entries for games that you can have.
They go chronologically, so whatever game you put first will be "launch/1"
and so on and so forth.

The later
part of the earlier line is this:
<img src="img/standard.png" width="229" height="150" border=0>

This displays an image for the link. If you want text instead,
the line
should look like this :
<a href="x-avefront://---.dream/proc/launch/1">Start Game</a>

XDP will allow you to set up as many pages as you want on a
disc, so your
disc can be as complicated or as simple as you want, and you CAN launch
games from pages other XDPDEX.HTML.

3. Hack the binaries. Now, I'm not
sure if this is entirely necessary for it
to be done this way, but all of the guides I read on multidiscs explained
it like this. Each binary must be binhacked
with the IP.BIN. The XDP binary
must be the last file to be binhacked, though.

And that's it. Easy enough.
